Mostly the beta versions of new Android flavors are limited to Google’s own devices only, but thanks to Project Treble it’s now possible for other non-Google users to enjoy the beta version of Android P on their devices – and one such group is the one using the Vivo X21 and its counterpart, Vivo X21 UD.

Vivo users can download the system images from the official Android P Developer page: https://dev.vivo.com.cn/

These updates are not provided as OTA (over the air) as the development process is still underway and there might be some bugs in the system.

After the current beta, the Vivo X21 and X21 UD will also receive two more beta updates on June 15th and July 30th, after which the stable version will be outed, probably somewhere in August or September.

Vivo X21 and X21 UD at a Glance

The Vivo X21 and X21 UD features a massive 6.28-inch Super AMOLED screen at a 1080 x 2280 resolution and an aspect ratio of 19:9. It runs on Android 8.1 Oreo / Android P Beta with Vivo’s own Funtouch OS 4.0 layered on top.

The phones launched in China and some other markets have 6GB RAM and 128GB storage coupled with Qualcomm’s Snapdragon 660 chipset. This hardware is powered by a 3200mAh battery.

Both phones have a primary Dual 12 MP (f/1.8, 1/2.5″, 1.4µm, Dual Pixel PDAF) + 5 MP (f/2.4) camera setup with phase detection autofocus and LED flash. While there is a 12 MP, f/2.0 Selfie camera on the front.

The major difference between the two phones is the placement of fingerprint scanner. The X21 has a regular fingerprint scanner pad on the back side, where X21 UD embeds the scanner under the display. Both phones feature Bluetooth 5.0 and super-fast charging as well.

The prices for these phones in the international markets are approximately Rs. 58,000 for X21 and Rs. 70,000 for the UD variant.
